Some tool authors are very concerned about the assignments of credits to their work.
I think in the contribtool process should offer a set of standard choices that can be checked off for each author
These standard choices could be from the following set:
1) developed (parts) of the core simulation engine
2) developed (parts) of the graphical interface
3) defined simulation tool and user requirements
4) managed the tool integration
5) Other – free form text
